Warren Haynes will take part in the Jerry Garcia Symphonic Celebration. He has Garcia’s Wolf guitar.

Jerry Garcia died in 1995, but his music with the Grateful Dead lives on — and so does Garcia's well-known Wolf guitar, which he used in the mid-'70s.

Warren Haynes has it now. The longtime guitarist for the Allman Brothers Band and founding member of Gov't Mule regularly tours with remaining members of the Dead.

Haynes, the Wolf and a 43-piece orchestra will be at the Riverside Theater on Wednesday for a Jerry Garcia Symphonic Celebration,one of six shows happening this spring. A jam band symphony? Sure, it sounds kind of weird. But the concert is curated by the Garcia family, and Haynes has promised the Dead spirit will live on at the shows, with rock-band jams and guitar solos over the orchestra. Even some of the orchestral arrangements are based on live Dead shows, not recorded material. Garcia was the most openminded of musicians, so he'd be nodding in approval.

Reserved seats for the 8 p.m. show are $45.50 and $55.50 at the box office, 116 W. Wisconsin Ave., (414) 286-3663 and pabsttheater.org.
